Texas Instruments TPS54140A /TPS54160A | Demoboard TIDA-00363
3.5V to 42V Input, 1.5A Step-Down Converter with Eco-Mode
Overview
| Topology | Other Topology |
| IC revision | 001 |
Description
The TIDA-00363 TI design provides a solution for EMC-compliant resolver-to-digital converter (RDC) with single-chip PGA411-Q1 with 12-bit angle resolution. PGA411-Q1's integrated boost-converter and exciter amplifier reduces system cost and board space compared to traditional RDC solutions. On-chip protection and diagnostic improve robustness against short-circuit and increase safery by detecting external fault conditions. A high-speed 3.3V SPI interface allows PGA411-Q1 configuration, diagnostics, angle and velocity information. Example firmware on a C2000 MCU allow for easy real-time evaluation of the TI design with angle data available at 16kHz sample rate for angle data read-out and register configuration through virtual COM port
